Solution
The spark plug may be damaged, remove it and check for
dirt and cracks. Replace with a new spark plug.
Push primer bulb until bulb is full of fuel. If bulb does not
fi ll, primary fuel delivery system is blocked. Contact a
service dealer. If primer bulb fi lls, engine may be fl ooded
(see next item).
Turn the on/off switch to the "O" (off) position and
completely remove the spark plug from both the engine
and the spark plug boot. Turn the product so that the
spark plug hole is aimed at the ground. Make sure the
choke lever is set to
14 times. This clears excess fuel from the engine. Clean
and reinstall the spark plug. With the throttle trigger fully
depressed, pull the starter cord 3 times. If the engine
does not start, set the choke lever to
normal starting instructions. If the engine still fails to
start, repeat the procedure with a new spark plug.
